The new house is 4,300 square feet, prompting Ling, Song and their designer to seek ways of reducing the home's carbon footprint. DiMaccio worked in 64 photovoltaic panels, some deployed as terrace shade outside the master suite. Lithium-ion batteries store power in the garage and return excess electricity to the grid.
